Perhaps you should try some spelling variations:
di letteratura » e letteratura, della letteratura
de letteratura » e letteratura, de litteratura, de litterature
de literatura » de litterature, la literatura, y literatura
grand libro » gran libro, grand livre
i grundei » i grunde, i grund
i grand » i grunde

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( i grundei libri ((di letteratura) OR (de literatura)) arti ) OR ( i grand libro de letteratura e )).
• Adding a wildcard symbol may retrieve word variants: (( i grundei libri ((di letteratura) or (de literatura)) arti ) or ( i grand libro de letteratura e ))*.
